Biomarque focuses on the development, validation and licensing of handheld (sports) medical devices for the continuous monitoring of biomarkers. Through the use of a series of micro-needles and specific coating techniques, Biomarque is able to measure biomarkers in intracellular body fluids. The first application is the monitoring of lactate as a biomarker to determine the lactate optimum during endurance sports. Other uses for lactate are monitoring patients in the intensive care unit and during operations. After a successful market introduction, Biomarque will concentrate on the adaptation of the system to monitor other biomarkers.
